Description

Feature

Tracking issue for enabling

[tool.mypy]
enable_error_code = ["explicit-override"]

When

strict = true

Pitch

As explained in PEP 698, strict enforcement of @override has many benefits.

When the Mypy developers feel that @override usage has had enough time for adoption in the community, enabling this by default when the user opts into strict mode would be helpful.

Research direction

Start by reviewing how the [tool.mypy] strict = true setting expands into enabled error codes, along with discussions #14072, #14609, and #1888. Confirm the adoption decision, update the strict-mode behavior and its tests so explicit-override is enabled by default, and verify that existing explicit configuration remains correct.
